The installation of a domestic safety unit is compulsory.
In order to avoid water dropping on the tank, the
domestic safety unit should not be placed directely
above the tank.
The third domestic water outlet can be used as a
return from the domestic hot water circulation loop.
Mains water kits could be in some countries due to
approval regulations.
To avoid all risk of corrosion connect the sanitary tank
directly in the earth.
Recommendations
• The pipe feeding the tank with cold water must be fitted
with a safety unit comprising at least the following:
- An isolating valve [
1
]
- a non-return valve [
3
]
- a safety valve [
4
]:
(set to < 10 bar)
- a sanitary expansion vessel of appropriate dimensions.
• When the operating pressure exceeds 6 bar a pressure
reducer [
2
] must be installed before the safety unit.
• Union fittings are recommended for easy removal of the
connections. Ideally the “dielectric” version is preferable
in order to protect the connections against corrosion in
the presence of dissimilar metals such as copper and
galvanised steel.
• The installation of an expansion vessel avoids safety valve
runoff (loss of water).
• Domestic hot water expansion vessel capacity:
5 Litres: for the following models:
100
8 Litres: for the following models:
130 / 160
12 Litres: for the following models:
210 / 240
Please see the technical instruction manual of the
expansion vessel’s manufacturer for further details.
